I smoked between 3-5 PACKS a day (the 5a day was when I was really stressed) I found myself at times buying a carton of smokes on Monday after work, and by Tuesday when I came home there would be only 2-3 packs left in the carton, my wife smokes too, but after I quit she bought a carton, and it lasted her TWO WEEKS! So I was a pretty heavy smoker, and am a heavy vapor. I have at times found myself having emptied a newly filled, inserted tank in under 15 minutes. What is that like 1.5 ml, well I fill them 3/4 full so they drain well. But I do go through ALOT sometimes. I was just at church, waiting on my wife. I was out in the car surfing this site, for an hour, and ended up emptying one new tank cart, refilling it, and by the time I got home that one was empty as well. So in less then an hour and a half.....3ml.
I VAPE 24MG. When I first started I bought 90ML of 16MG, and it made me feel sick, actually physically sick. I felt "chemically" all over, I wanted to smoke so bad, thought that this vaping thing was a HUGE mistake, couldn't stand to inhale anymore, and didn't know what I ever saw in it (when I first started I had a plain bottle of clear juice from a friend, I have no idea what was in it, or the strength. But I will say that I could BARELY VAPE it. I definatley couldn't chain VAPE it. When I did.......I felt like I had smoked way to much) my wife was going to try vaping, but thought 16 was WAY too low for her, so I ordered her some 24MG menthol juice, and I started chain vaping that when I got it. All of those symptoms went away! My chemically feeling went away, I LOVED vaping again, and all of that. The 24 didn't do it for my wife, so I then purchased 36MG for her, and when that came in, WOW i also got my new tank system with that order, and I was way more excited about the juice. Jenny vapes the 36 all day, I VAPE it every now and then only when I'm REALLY CRAVING, but everyone is different.
Think about it, when I smoked, on really bad days I would smoke up to 200 cigarettes a day! I literally chain smoked all day, I haven't added up how much I VAPE, but I'm guessing it would be between 6-12 tank cartridges.
